Step‑by‑Step Instructions for French Lobster Thermidor Delight
Step 1: Prep Lobsters
Begin by bringing a large pot of salted water to a boil. Carefully add the live lobsters and let them cook for 8–10 minutes, until they turn bright red. Once cooked, transfer them to a bowl of ice water to halt the cooking process. Allow them to cool, then crack open the shells and remove the tender lobster meat, setting it aside for the filling.
Step 2: Sauté Aromatics
In a large skillet, melt 2 tablespoons of butter over medium heat. Once melted and bubbly, add finely chopped shallots, sautéing until they’re translucent and fragrant, about 3–4 minutes. Next, incorporate sliced mushrooms into the skillet, stirring occasionally until they soften and turn golden, which should take roughly 3–5 minutes.
Step 3: Create Sauce
Pour in 1/2 cup of white wine and bring it to a gentle simmer. Cook until the liquid reduces by half, around 5–7 minutes. Once reduced, stir in 1 cup of heavy cream and continue cooking for an additional 3–4 minutes, allowing the sauce to thicken slightly. You’re aiming for a luxurious creamy consistency that coats the back of a spoon.
Step 4: Incorporate Lobster
Chop the cooked lobster meat into bite-sized pieces and gently fold it into the creamy sauce. Add 1 teaspoon of paprika and half of the grated Parmesan cheese, stirring to combine. Season with salt and pepper to taste; this is your moment to taste the rich flavors of the French Lobster Thermidor Delight and adjust as you like.
Step 5: Fill Shells
Using a spoon, carefully transfer the luscious lobster mixture back into the cleaned lobster shells. Make sure to pack it in lightly, forming an even mound on top. Sprinkle the remaining Parmesan cheese over the filling, creating a beautiful layer that will melt and crisp up during broiling.
Step 6: Broil
Preheat your broiler to high. Place the stuffed lobster shells on a baking sheet lined with foil and slide them under the broiler. Broil for 3–5 minutes, keeping a close eye on them until the tops turn golden brown and bubbly. This final step adds a deliciously crunchy texture to your already divine French Lobster Thermidor Delight.
Step 7: Serve
Remove the Lobster Thermidor from the oven and let it rest for a couple of minutes. Serve hot, ideally with a crisp salad or slices of crusty bread to soak up the rich sauce. Enjoy the delightful experience of your homemade French Lobster Thermidor with family and friends!

French Lobster Thermidor Recipe FAQs
What kind of lobster should I use for French Lobster Thermidor?
